DETAILED DESCRIPTION OF THE INVENTION

To explain the technical contents, structural features, achieved objectives and effects of the technical solutions in detail, the following detailed description will be illustrated with reference to the embodiments and the drawings.

Referring to FIG. 1, in this embodiment, U-KEY is inserted on the client tool. In this embodiment, the client tool is PC, wherein the U-KEY stores the operator certificate and operator private key. When the U-KEY is inserted on the client tool, and interactive software is installed on the client tool, so that the client tool can obtain the operator certificate from the U-KEY and directly use the operator private key. Secondly, in this embodiment, a specific APP is installed on the PC. In the APP login interface, the maintenance personnel need to input the account and password to log into the system; by logging into the system through account and password, the server will determine the authority of the account and password, thereby ensuring the legality of the account.

In other embodiments, it also may directly input the specific website through the browser, and similarly, the maintenance personnel are required to input the account and password to log into the system.

The specific implementation steps are as follows: Step S101, generating a first public-private key pair Pr1 and Pu1 and a second public-private key pair Pr2 and Pu2. Firstly, we ensure that the terminal, server and the client tool are connected to the Internet. After connected to the Internet, the server generates the first public-private key pair Pr1 and Pu1 and the second public-private key pair Pr2 and Pu2, and sends the first public key Pu1 and the second public key Pu2 to the terminal. Namely, step S102: presetting the first public key Pu1 and the second public key Pu2 on the terminal. Meanwhile, the U-KEY is issued, the second private key Pr2 is stored into the U-KEY from the server, and the client tool may obtain the second private key Pr2 from the U-KEY through the installed interactive software. Namely, step S102: presetting the second private key Pr2 to the U-KEY.

Presetting the first public key Pu1 on the terminal is to pass the account authority and the legality authentication of U-KEY in step S103 to step S106, and subsequently, the process processes to step S107. Namely, the server obtains the second to-be-authenticated data from the terminal, and the server determines the legality of the second to-be-authenticated data. After confirming the legality, the server uses the first private key Pr1 to encrypt the second to-be-authenticated data to generate the second authentication data. Step S108: the server returns the second authentication data to the terminal. Step S109: the terminal authenticates whether the second authentication data is passed, namely the terminal may use the preset first public key Pu1 to decrypt the second authentication data, obtain the plaintext of the second authentication data, and compare whether the plaintext of the second authentication data is consistent with the second to-be-authenticated data; and if they are consistent, the authentication is passed. After passing the authentication, the process processes to step S110. Namely, sending an instruction of obtaining the alarm information log, namely the client tool sends the instruction of obtaining the alarm information log to the terminal, and the terminal receives the instruction to obtain the alarm information log. In addition, in step S111, encrypting the attack alarm information log, namely the terminal uses the preset second public key Pu2 to encrypt the attack alarm information log to ensure the security of the attack alarm information log during the data transmission process. After the encryption is complete, the terminal sends the attack alarm information log to the client tool. Step S112: the client tool decrypts the attack alarm information log by using the preset second private key Pr2 to get the plaintext.

During the whole process, firstly determining whether the account of the maintenance personnel has the authority of obtaining the attack alarm information log. If yes, then determining the legality of U-KEY of the operator. The two-factor authentication of account and U-KEY greatly ensures the security of the instruction of obtaining the attack alarm information log. In addition, the instruction of obtaining the attack alarm information log from the terminal is a lawful act approved by the server, ensuring the legality of the operation to obtain the attack alarm information log. Moreover, the obtained attack alarm information log is encrypted by the second public key and needs to use a specific second private key to decrypt, thus further enhancing the security and confidentiality of the attack alarm information log, and solving the problem that some lawbreakers can easily get the attack alarm information log.

The step S103 is as follows: performing account login authentication. In this embodiment, a specific APP is installed on the client tool; in the APP login interface, the maintenance personnel can input the account and password to log into the system.

Among them, the server stores all legal accounts and passwords, including the corresponding authority of these accounts. Step S104: determining whether the account has the authority of obtaining the attack alarm information log, and the specific steps are as follows: the maintenance personnel input the account and password, and the server obtains the account and password input by the maintenance personnel, and determines whether this account and password are stored in the server. If yes, the maintenance personnel successfully log into the system; and meanwhile the server further obtains the authority of this account, and determines whether this account has the authority to obtain the attack alarm information log. Through the authority authentication on the account and password by the server, the legality of the subsequent operations is ensured.

After authenticating that the account has the authority of obtaining the attack alarm information log by the server, the process processes to step S105: authenticating the legality of the U-KEY of operator. The specific steps are as follows:

The client tool obtains the first to-be-authenticated data; firstly, the server generates the first to-be-authenticated data. In this embodiment, the first to-be-authenticated data is a 16-byte random number. The client tool obtains the first to-be-authenticated data from the server.

In other embodiments, the first to-be-authenticated data also may be a random number in other bytes, which may be a combination of 32-byte letters, numbers, special signs, etc. In this embodiment, by generating a 16-byte random number every time, ensuring that the random number generated every time is different.

The client tool uses the U-KEY to generate the first authentication data; after receiving the first to-be-authenticated data, the client tool uses the operator private key stored in U-KEY to encrypt the first to-be-authenticated data, and the first authentication data is generated after encryption. By using the operator private key stored in the U-KEY to encrypt the first to-be-authenticated data, it is ensured that the generated first authentication data will not be intercepted by other illegitimate U-KEYs during the data transmission process to impersonate the truly legitimate U-KEY and trigger security problems.

After generating the first authentication data, the client tool sends the first authentication data and operator certificate to the server for authentication, namely step S106: determining whether U-KEY is legality; the authentication herein refers that the server obtains the plaintext by decrypting the received first authentication data and compares whether the plaintext is consistent with the first to-be-authenticated data on the server. If yes, the U-KEY has passed the authentication of the server and obtained the approval of the server. Namely, the U-KEY has obtained the authority of obtaining the information from the server and sending the information to the server. Among them, the operator certificate sent here contains the public key that can decrypt the first authentication data, so that the server can extract the public key inside the operator certificate after receiving the operator certificate, and then decrypt the first authentication data. For example, if the first to-be-authenticated data is D1, using the operator private key S to encrypt D1 to generate the first authentication data: D2; the public key corresponding to the operator private key S is G. The attack cleanup tool sends D2 and the certificate containing G to the server, and the server extracts G from the certificate and uses G to decrypt D2 and obtain the plaintext information of D2. Comparing whether the plaintext of D1 and D2 is consistent. If yes, the U-KEY passes the authentication of the server; if not, the U-KEY does not pass the authentication of the server.

After the server confirms that the U-KEY is legal, the process processes to step S107: obtaining the second to-be-authenticated data. The specific steps are as follows:

The client tool obtains the second to-be-authenticated data from the terminal; similarly, the terminal generates the second to-be-authenticated data. In this embodiment, the second to-be-authenticated data is a combination of the terminal serial number, mainboard feature code and random number. The terminal serial number and mainboard feature code here are unique and can uniquely identify a terminal. In this embodiment, the random number is a 16-byte random number. In other embodiments, the random number may be letters or characters in other digits. The uniqueness of the second to-be-authenticated data is ensured by using the combination of the terminal serial number, mainboard feature code and random number with uniquely identified terminal.

After the terminal generates the second to-be-authenticated data, the client tool obtains the second to-be-authenticated data.

After obtaining the second to-be-authenticated data, the client tool sends the second to-be-authenticated data to the server; and the server determines whether the information of the terminal equipment is legitimate by authenticating the second to-be-authenticated data. If yes, the server uses the first private key Pr1 to encrypt the second to-be-authenticated data to generate the second authentication data.

In this embodiment, considering the high safety requirement, as the public key used by every terminal is different, when the server determines the terminal information, it not merely determines its legality, but also uses the private key corresponding to the terminal to encrypt the to-be-authenticated data according to the terminal information. Through encrypting the to-be-authenticated data by using the private key, it is ensured that the generated authentication data will not be intercepted by other lawbreakers during data transmission process to impersonate the truly legitimate server to cheat the terminal and cause any security problem.

While in some other embodiments, considering the convenience and universality, the public key used by every terminal is the same. Thus, the server only needs to determine the legality of the terminal information; and the server uses a general private key to encrypt the to-be-authenticated data.

Step S108: returning the second authentication data. The specific steps are as follows: The server sends the second authentication data to the terminal through the client tool, and the terminal authenticates the second authentication data. Namely, step S109: determining whether the second authentication data has passed the authentication. The specific steps are as follows: The terminal uses the first public key Pu1 preset in step S102 to decrypt the second authentication data to obtain the plaintext of the second authentication data, and compares whether the plaintext of the second authentication data is consistent with the plaintext of the second to-be-authenticated data. If yes, the authentication passed.

If the authentication is passed, it means the server also passes the authentication of the terminal. Then the U-KEY holder approved by the server has the authority to use the client tool to send the instruction of obtaining the attack alarm information log to the terminal (namely step S110). Among them, the instruction at least includes: operating as per instruction of obtaining the attack alarm information log from the terminal, thus avoiding illegal operations. In addition, in order to ensure the security of the attack alarm information log during the data transmission process, in step S111, the attack alarm information log is encrypted. The terminal here uses the preset second public key Pu2 to encrypt the attack alarm information log. After that, the terminal sends the attack alarm information log to the client tool.

Step S112: decrypting the attack alarm information log to obtain the corresponding plaintext. The client tool receives the attack alarm information log and uses the preset second private key Pr2 to decrypt the attack alarm information log to obtain the plaintext. After the U-KEY passes authentication of the server, the subsequent steps all can be completed automatically, which greatly improves the speed of obtaining the attack alarm information log.

Referring to FIG. 2, in some embodiments, according to the present invention, the scheme of a system for authorizing acquisition of an attack alarm information log of a terminal is as follows:

The system includes: a server 10, a terminal 20 and a client tool 30. Among them, the U-KEY40 is inserted into the client tool 30. In this embodiment, the client tool 30 is PC. an operator certificate 401 and an operator private key 402 are stored in the U-KEY40. After U-KEY40 is inserted into the client tool 30, as an interactive software is installed on the client tool 30, the client tool 30 can obtain the operator certificate 401 and the operator private key 402 through the interactive software.

The details are as follows:

The server 10 is used for generating a first public-private key pair Pr1 and Pu1 and a second public-private key pair Pr2 and Pu2, and sending the first public key Pu1 and the second public key Pu2 to the terminal 20. Meanwhile, when the U-KEY40 is issued, the second private key Pr2 is stored into the U-KEY40 from the server.

The client tool 30 is used for obtaining the second private key Pr2 through the installed interactive software from the U-KEY40.

In this embodiment, a specific APP is installed on the client tool 30. In the APP login interface, the maintenance personnel input the account and password to log in to the system.

The server 10 stores all valid accounts and passwords, including the corresponding authorities of these accounts. The maintenance personnel input the account and password, and the server 10 obtains the account and password input by the maintenance personnel, and determines whether such account and password are stored in the server 10. If they are stored in the server 10, the maintenance personnel successfully log in to the system; and meanwhile, the server 10 further obtains the authority of such account, and determines whether such account has the authority to obtain the attack alarm information log. Through the authority authentication on the account and password by Server 10, the legality of subsequent operations is ensured.

After authenticating that the account has the authority to obtain the attack alarm information log, the server 10 authenticates the legality of the operator U-KEY40. The details are as follows:

The client tool 30 obtains the first to-be-authenticated data from the server 10; firstly, the server 10 generates the first to-be-authenticated data. In this embodiment, the first to-be-authenticated data is a 16-byte random number. The client tool 30 obtains the first to-be-authenticated data the server.

The client tool 30 uses the U-KEY to generate the first authentication data; after receiving the first to-be-authenticated data, the client tool 30 uses the operator private key 402 stored in U-KEY to encrypt the first to-be-authenticated data, and the first authentication data is generated after encryption. Through the operator private key 402 stored in the U-KEY, the first to-be-authenticated data is encrypted, which ensures that the generated first authentication data will not be intercepted by other unauthorized U-KEY40 during the data transmission process to impersonate the truly legitimate U-KEY40 and trigger security problems.

After the first authentication data is generated, the client tool 30 sends the first authentication data and operator certificate 401 to the server 10 for authentication. Such authentication refers to “that the server 10 obtains the plaintext by decrypting the received first authentication data, and compares whether such plaintext is the consistent with the first to-be-authenticated data of the server 10”. If they are consistent, the U-KEY40 passes the authentication of the server 10 and obtains the approval of the server 10. In other words, the U-KEY40 obtains the authority to obtain information from and the server 10 send the information to the server 10.

After the server 10 confirms the legality of the U-KEY40, the client tool 30 obtains the second to-be-authenticated data from the terminal 20; similarly, the terminal 20 generates the second to-be-authenticated data. In this embodiment, the second to-be-authenticated data is a combination of the terminal serial number, mainboard feature code and random number. Such terminal serial number and mainboard feature code are unique and can uniquely identify a terminal 120. Through using the combination of terminal serial number, mainboard feature code and random number with uniquely identified terminal, the uniqueness of the second to-be-authenticated data is ensured.

After the terminal 20 generates the second to-be-authenticated data, Client Tool 30 gets the second to-be-authenticated data.

After obtaining the second to-be-authenticated data, the client tool 30 sends the second to-be-authenticated data and terminal information to the server 10; and the server 10 determines whether the information of the terminal equipment is legitimate by authenticating the second to-be-authenticated data. If such information is legitimate, the server 10 uses the first authentication private key Pr1 to encrypt the second to-be-authenticated data to generate the second authentication data.

Through the client tool 30, the server 10 sends the second authentication data to the terminal 120 for authentication. The details are as follows: the terminal 20 uses the preset first public key Pu1 to decrypt the second authentication data to obtain the plaintext of the second authentication data, and compares whether the plaintext of the second authentication data is consistent with the second to-be-authenticated data. If they are consistent, the authentication passed.

If the authentication is passed, it means that the server 10 also passes the authentication of the terminal 20. Then, the U-KEY40 holder approved by the server 10 has the authority to send the instruction of obtaining the attack alarm information log to the terminal 20 through the client tool 30. The instruction at least includes: operating as per instruction of obtaining the attack alarm information log from the terminal 20, thus avoiding illegal operations. In addition, in order to ensure the security of the attack alarm information log during the transmission process. The terminal 20 is also used for encrypting the attack alarm information log by the preset second public key Pu2, and sending the attack alarm information log to the client tool 30 after encryption.

The client tool 30 is also used for receiving the attack alarm information log, and decrypting the attack alarm information log by the preset second private key Pr2 to obtain the plaintext. After U-KEY40 passes the authentication of the server 10, the subsequent steps all can be completed automatically, which greatly improves the speed of obtaining the attack alarm information log.

In all embodiments of the present invention, if the authentication is invalid or the account has no corresponding authority, the method is ended prematurely, and the data stream in the system will not flow to the next module.
